Caring for Lithodora diffusa 'Heavenly Blue'

(Formerly Lithospermum)

These are immensely popular, prostrate, and spreading plants which are many branched, low growing and evergreen. ‘Heavenly Blue’ is perfectly hardy in the border, rockery or growing away happily in a tub, container or window box. Its appeal of course comes from its multitude of azure-blue flowers which go on and on from late spring and long into summer. About 6in is its maximum height with an ultimate spread of, say, 24in. The leaves are narrow and oblong, deep green in colour, and covered in tiny white hairs.

This is a greedy little plant which likes an improved or well mulched or peaty soil. This is a very easy plant to propagate from cuttings and older clumps will have some bare patches and straggly growth eventually so this is probably a plant to restart every few years and dig out the older ones.
